Do you ever wonder where all of your favorite skin-care products and techniques come from? Not whom you learned them from or who makes them, but how they were invented? You might not even realize that your exfoliation routine, in particular, was likely originated in ancient Egypt.

"In my book, these royal highnesses were the OG skinfluencers," she says in the first installment of the new video series entitled, Allure Skinfluencers. "The queens used salt from the sea to smooth and rejuvenate their skin — thousands of years later, their insight still holds true with today's science."
